FaxBurner offers a genuinely free fax number and a polished mobile app — but the free plan's 5-page lifetime sending limit and lack of HIPAA compliance leave a lot to be desired. Here's the honest breakdown before you sign up.
Frequently Asked Questions
Is FaxBurner really free?
FaxBurner has a free tier that lets you receive up to 25 pages/month and get a temporary fax number valid for 24 hours. However, free-plan sending is limited to 5 pages total — this is a lifetime limit, not monthly. Most users who need to send more than one fax will need the $12.95/mo plan.
Is FaxBurner HIPAA compliant?
No. FaxBurner is not HIPAA compliant on any plan and does not offer a Business Associate Agreement (BAA). It should not be used to transmit protected health information (PHI). For HIPAA-compliant faxing, consider [mFax Business](https://mfax.to/business/) starting at $20.99/month.
How long does a FaxBurner number last?
Free plan numbers expire after 24 hours. Once the number expires, a new (different) number is issued — you cannot keep the same number on the free plan. Paid plans ($12.95/mo and up) include a permanent toll-free fax number that doesn't expire.
Can FaxBurner send international faxes?
No. FaxBurner can only send faxes to US and Canadian numbers. It can receive faxes from anywhere in the world. If you need to send international faxes, look at alternatives like [mFax](https://mfax.to) or eFax.
What are the best FaxBurner alternatives?
The best FaxBurner alternatives are mFax (mobile-first, HIPAA-compliant, free to try), Fax.Plus (free tier, from $6.99/mo, HIPAA on paid plans), and eFax (enterprise-grade, from $18.99/mo). For casual mobile faxing, [mFax](https://mfax.to) is the strongest competitor at a comparable price point with better security.
